Dev Flutter with firebase on a M1 Mac

I had some issues with using firebase, google_sign_in plugin with flutter on M1 MacBook Pro.

I had tried so many methods but neither of them worked.

Here i got some errors when building iOS apps with Flutter (firebase and google_sign_in plugin)

    /Users/alex/development/flutter_apps/time_tracker_flutter_course/ios/Pods/FirebaseCoreDiagnostics/Firebase/CoreDiagnostics/FIRCDLibrary/FIRCoreDiagnostics.m:20:9: fatal error: could not build module 'GoogleDataTransport'
    #import <GoogleDataTransport/GoogleDataTransport.h>
     ~~~~~~~^

Could not build the application for the simulator.
Error launching application on iPhone 13.

As you can see it lacks of *.h header files.　　

I wrote a tutorial before , here: 

Using Flutter 2 on M1 MacOS Apple Silicon

Yes it works well. But if I want to use google_sign_in plugin and firebase, I will have some compiling error.

you need to install homebrew firstly.

Source from: https://codecrew.codewithchris.com/t/solved-install-cocoapod-on-m1-mac-sudo-gem-install-ffi-fail/15648

Then reinstall it.

brew reinstall libffi
# or
brew install libffi

Then

# uninstall using gem, which comes with macOS
sudo gem uninstall cocoapods
# reinstall using homebrew. it comes with a command-line tool called: pod
brew install cocoapods

Then go to you flutter app

flutter clean
flutter pub get

Then run without debug from your vscode editor of the Flutter project.

Check the Debug Console.

You can compile and run the app successfully.

If you see some error like this when you are using Flutter and Firebase, google_sign_in plugin,

IPHONEOS_DEPLOYMENT_TARGET is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.0.99

Xcode 12 drops support for iOS 8 and how to fix deployment target warnings in CocoaPods

https://www.jessesquires.com/blog/2020/07/20/xcode-12-drops-support-for-ios-8-fix-for-cocoapods/

I'm using Xcode 13.2.1, simulator iPhone 13, iOS 15.2

I changed the Podfile to be

# platform :ios, '9.0'

platform :ios, '12.0'

...

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
     end
  end
end

Because I hardcode it to be ios 12.

Yes. Minimum ios support down to 12. It's year 2022 now.
